WATER-HEATER.

SPECIFICATION forming part of Letters Patent N 0. 705,335, dated July 22, 1902. Application filed January 22.1902. Serial No. 90,742. (No model) I To all whom it mag concern:

Be it known that I, JOSEPH Fosrnn, a citizen of the United States, and aresident of New York city, in the borough of Brooklyn, county of'Kings, and State of New York, have invented certain new and useful Improvements in Water-Heaters, of which the following is a specification, taken in connection with the accompanying drawings, forming showing a modification. Fig. 3 is a side View of the same.

In general terms this water-heater comprises interlocking valves by which'the' cold water and heating fluid are admitted to an injector. From this point the heated water passes into a mixing-chamber, in which it is thoroughly mingled to give a uniform temperature throughout all parts of the stream of water. The mixing-chamber A is formed of metal in any desired way and has the generally circular form indicated in Fig. 1. The chamber is formed with a supporting'bracket A, secured to one side of the same, by which the heater may be supported. The lower end of the chamber is formed with a screw connectionA by which it is joined to the collar B at the upper end of the injector B. The

inlet A of the mixing-chamber is flared out-- ward, as indicated, and the deflecting-plate A is provided opposite this inlet, This den fleeting-plate is given thesubstantially cir-.

cular form indicated,-this plate beingshown substantially concentric with the outer wall The two guidingof the mixing-chamber. plates A are also formed in the mixing-chamber and'are given a curved form, so as to extend downward from the upper end ofthev chamber and curve around the upper ends of the deflecting-plate A The lower ends of these guiding-plates A curve outward, so as to guide the water into contact with the-defleeting-plate and to cause the impingement of the water against this plate at a considerable angle. In this way violent eddies are set up within the space A and the mass of waterpasses out between the two guidingplates into the upper space A From thence the thoroughly-mixed and uniformly-heated 'water'isled off through the outlet A diametrically arranged with respect to the inlet vice. It willbe understood that the deflect ing-plates and guiding-plates form partitions which extend the entire depth of the circular mixing-chamber, although, if desired, sinuous passages might be formed in the mixingchamber by employing partitions of different shape.

The support F is arranged at the lower end of the heater, and the holes F l? in this support are engaged by the water-valve I) and by the heating-valve E. It will be of course understood that in using this water-heater the water-valve is connected with a waterpipe' to give a continuous flow of water, and

the heater-valve'E is connected with a source of hot water or preferably with a source of steam. The water-valve D is of ordinary construction, being formed with the valve-seat D, againstwhich thevalve-plug D acts, this valve-plug being secured to the water-valve stem D having the threaded portion D upon it and having the water-handle D rigidly secured to the outer end of the same. The threads on the valve-stem govern the position of the valve, and a suitable packed joint is provided at D, as is usual in this art. The

'water-valveD is secured to the injector B, so

as'to supply Water to the curved passage B of the injector. The heating-valve E is also secured to this injector tosupplyheating fluid to the heating-nozzle B screwed into the straight passage B of the injector, so as to be substantially in line with the inlet A of the mixing-chamber. The heating-valve is formed with a valve-seat E, upon which the heating pl'ug E acts, this plug being'secured to the tubularheating-valve stem E having the threads E formed upon it. Upon the outer end of this heating-valve stem is rigidly secured the heating-handle E The packed joint E is provided at the rear end of the heating-valve, so as to prevent any leakage A to a shower-bath or any other desired deabout the stem of the water-valve, which, as is seen, passes through the heating-valve and through the hole in the heating-valve stem. The water-handle is formed smaller than the heating-handle, so that either one may be readily grasped to operate the valves, and it will be seen, furthermore, that the central shoulders of these handles abut when both valves are closed. In this way it will be apparent that a very simple and desirable form of interlocking valve is provided for this purpose, since the threads on both the valvestems are righ t-handed, as indicated, and thus in the closed position of the valves (indicated in the drawings) the heating-handle is locked. and the heating-valve cannot be opened until the water-handle is operated to open the water-valve. Also the heating-valve must be closed before the water-valve can be completely closed. Thus it is impossible to waste the heating fluid or to get unduly hot water from the water-heater.

The operation of the heater in case steam is used tends to increase the force of water issuing from the heater, since the steam as it issues from the heating-nozzle B is entirely condensed by the cold water in the injector, and the force of the steam operates to urge the water through the inlet to the mixingchamber, so that a very considerable increase of head is thus secured.

In Figs. 2 and 3 a modified form of interlocking valves is indicated. The water-pipe G is controlled by the globe-valve G of ordinary construction, the valve-stem G2 of this valve having rigidly secured upon it the Water-handle G This water-handle is provided with a circumferential slot G", which extends substantially half round the same, the threads upon the valve-stem being of a coarse pitch, so that the valve is entirely open after the valve-slem has revolved through a half-revolution. The stop-pin K engages the groove G, and this stop-pin is mounted upon the bracket K, secured to the water-pipe G and the heating-pipe H. The heating-pipe is governed by a similar valve having the heatinghandle H which is underneath the waterhandle G there being a slight overlap, as is indicated in Fig. 2. The heating-handle is also provided with a similar circumferential groove H, with which the stop-pin K engages. It will of course be understood that this arrangement of valves is connected with the injector B or with some similar mixing device. In operating these interlocking handles the water-handle is turned to any desired extent up to a half-revolution,and thereafter the handle H may be turned to admit the heating fluid to the heater. After the water-handle has been turned to admit water to the injector the heating-handle may be turned to the extent desired to admit the requisite amount of heating fluid to the injector, so that the water is heated to any desired extent. It will be seen that in this manner the interlocking handles govern the admission of fluids to the injector in varying proportions. In closing the valves it is necessary to turn the heating-handle first, and thereby to close the heating-valve. Thereafter the water-valve may be closed. Many other modifications of this water-heater may be made, and, furthermore, parts of this apparatus may be used without employing all of the same. I do not, therefore, Wish to be limited to the disclosure which I have made in this case; but

What I claim as new, and wish to secure by Letters Patent, is set forth in the appended claims:
